Price history
Roborock S8 Max Ultra with Refill & Drainage System specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
Consumables: a dust bag in the station, which lasts up to 49 days.
Suction and brushes 2 facts
- Suction power
Suction in pascal, as the maker measures it. More pascal helps on carpet, but it says little about how well the robot picks grit off a hard floor.
- 8,000 Pa
- Extending side brush
The side brush swings out in a corner or along a baseboard, so the dust there is swept in too.
- yes
Mopping 2 facts
- Mop type
How the mop is built: flat pads, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works.
- flat or vibrating pad
- Mop lift on carpet
How far the robot lifts the mop when it drives onto a carpet. From about 0.4 in (10 mm) a medium pile stays dry.
- 0.8 in (20 mm)
Dock 9 facts
- Empties the dust bin
The dock empties the robot’s dust bin, usually after every run. You only empty the dock’s bag or bin.
- yes
- Bagless
The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself.
- no
- Dust bag lasts
How long the maker says a dust bag lasts with daily use. With pets or a lot of carpet it is shorter.
- up to 49 days
- Washes the mop
The dock washes the mop for you, so you do not rinse it by hand.
- yes
- Wash temperature
How hot the dock washes the mop. Above 140 °F (60 °C) grease comes off, which is what keeps a mop from smelling.
- 140 °F (60 °C)
- Dries the mop
The dock dries the mop afterwards, so it does not sit there wet and start to smell.
- yes
- Hot-air drying
Drying is done with warm air instead of cold. It is faster and it helps against smell.
- yes
- Dispenses detergent
The dock mixes detergent into the water itself, from its own bottle.
- yes
- Plumbing hookup
The dock can be connected to the tap and the drain, so you never fill or empty a tank. It does need a connection nearby.
- yes
Navigation and obstacles 2 facts
- Navigation
How the robot maps your home and follows that map. Lidar measures with a laser and works in the dark, a camera looks along and recognizes more.
- LiDAR turret
- Obstacle avoidance
How the robot sees loose things on the floor, such as cables, socks or a pet accident. A camera with depth sensing sees more than a bumper that reacts on contact.
- AI camera
Robot 1 fact
- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.
- 3.8 in (9.7 cm)
Battery 1 fact
- Battery capacity
The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.
- 5,200 mAh
Smart features and warranty 1 fact
- Voice assistants
Which voice assistants the robot works with, such as Google Assistant or Alexa.
- Alexa, Siri, Google Home
